Overview

Engineering reference data for Wood Header Weight Supported in material science and properties.

$\sigma = \frac{F}{A}$

Force per unit area.

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Symbol	Description	Unit
$\sigma$	Stress	Pa
$\varepsilon$	Strain	—
$E$	Young's modulus	Pa
$\alpha$	Thermal expansion coefficient	1/°C
$\Delta T$	Temperature change	°C
